Hi Bean,

I think this patch is the first patch that adds a declaration in 
ufshcd.h that uses the enum dma_data_direction data type. That leads to 
the following compiler warning:

In file included from drivers/ufs/host/tc-dwc-g210-pci.c:10:
./include/ufs/ufshcd.h:1282:72: warning: ‘enum dma_data_direction’ 
declared inside parameter list will not be visible outside of this 
definition or declaration
  1282 |                                      struct scatterlist 
*sg_list, enum dma_data_direction dir);
       | 
        ^~~~~~~~~~~~~~~~~~

Can you please post a patch to fix this? Adding the following line is 
probably sufficient:

#include <linux/dma-direction.h>

This has been detected with the following script:

Thanks,
